Obviously, Dark Naruto would be one of the main characters. He is the center of this fanfiction concept. Other than him, characters like Sasuke would likely still play important roles. Sasuke might be either an ally or an adversary to Dark Naruto, depending on how the story is written. Also, characters like Kakashi Sensei could be there to try and guide or stop Dark Naruto, given his new, more dangerous state.
In this fanfiction, aside from Dark Naruto, there could be original characters created specifically for this story. They might be opponents that Dark Naruto meets in his 'gamer' - like adventures. For example, there could be a powerful, mysterious character who controls the virtual - like realms that Dark Naruto enters. And of course, the regular Naruto characters like Sakura would also be part of the story, perhaps trying to bring back the old Naruto from his dark state.
The main characters would include Dark Naruto, who is the focal point with his new 'gamer' abilities. Then there are his friends and foes from the original Naruto series. His friends like Shikamaru might try to understand and help him, while his foes, such as Orochimaru, could see Dark Naruto as a new opportunity to achieve their own evil goals. And there might be some new characters introduced as part of the 'gamer' world, like a guide character who gives Dark Naruto quests and tasks to complete.
